Editing Shadowrun (section)

===Australia===
Most of Australia is unpleasant to live in now, but in the Sixth World... hoo-boy. Dual-natured weather phenomena called "mana storms" are a fact of life, appearing out of nowhere, laying waste to an area, and disappearing just as suddenly. The Outback is even more hazardous thanks to these storms, which have herded people into the few major cities along the coasts. The city of Sydney is surrounded in a near-permanent mana storm that's cut it off from the rest of the world. Major landmarks like Uluru (Ayer's Rock) are home to powerful spirits that don't like visitors. The only civilizations that manage to survive outside the cities are the Aborigine tribes who have lived with the land instead of off of it.  What few critters that weren't deadly to humanity before now breath fire or are possessed, or both.

As for Tasmania, it went feral in the Awakening. The island no longer wants visitors. Nature has overrun what little remains of human civilization on the island and it fights back when people try to set up research or paracritter-breeding facilities.
